    • Chen had said that he intended to support S8's, but as obvious from his forum, he has not been very active (due to his project at work).

      If i was ever to go with an S8, that would have to be available, as it was one of the main reasons I finally got an 935F. The other main reason was Echoe here.

      I would like to know what can be done about this. I'd like to get a MM build working.

      I don't think this is the place to ask about another ROM - the Duelboot thread would be the best place.

      However, I can confirm that extsd slots have been a major problem with devices such as S7's. Best to try patching and flashing in any other slot that has enough room - suggest Data slots.

    • All was working good with respect to backup/restores until recently (with current an recent older APP's. It will not restore primary and secondary (data OK but not system) ROM, and others are hit and miss.

      Anyone else have issues recently ?

      Does this mean that we are able to use ext.slot for the S7/S7edge now? And if so, do we have to 'modify' anything else?

    • All right, these days I killed the phone with dualboot tests and;
      - all roms slot can be save (primary, data-slot 1,2,3) restored anywhere except primary
      - primary rom can be only updated because when you wipe the primary rom for restoring another save
      you delete the base of dualboot so.......the primary it's untouchable (from my descovery)
      - for update the primary you need to patch the upgrade and flash (all other rom will not be affected)

      @gaw even for primary to primary it's not working, sorry my friend

      Don't be sorry - you did a lot of work, and confirmed i was not doing anything wrong - it just doesn't work.

      So thanks again.



      I have an odd one: If I change network settings in any duelboot ROM, it carries over to the others.

      The reason I ran into this was because of CSC problems with the S8 ports in the US, which results in them disconnecting calls to other devices on the same network when answered. To get around this, I set the network to 3G in the Port, but then it is set that way everywhere - lol.
    • i have determined my Safetynet problems are Duelboot.

      I had no problems with it on Echoe thru v16, but i had not been patching it as primary - only flashing and setting kernel.
      For v17, I patched it as primary and Saftynet was out. Reflashed the unpatched version - Safetynet back.

      So no way i can get Saftynet working on my v8 Port or any other patched ROMs.

      Once you've added all the zips you want to flash,(if you flash rom and kernel, first flash rom and after kernel)
      click the check mark in the action bar and they will be flashed right away.(take your time and relax)
      when flash is finished, press back to roms menu (check if secondary rom have a green mark)if yes than it's OK
      Hi Friends! I have a problem. I'm using Echoerom v17 and am trying to install the S8port3. Did all the steps till "when flash is finished, press back to roms menu" but when i pressed back to roms menu does not appear to S8port3. What did I do wrong?

      Thanks!

      hi. Answer is on your screen shot. Look again at file I've attached, circled what's important.
      :)
      Ps. Steps you should take are as follows :
      - while on primary (v17) install mbtool and make sure it is up to date
      - patch S8port rom zip file per your needs
      - reboot to recovery and flash patched zip
      Done.
      :)
